To all whom, it may concern the aforesaid strain.

To obclear, and exact description. viate thisdefect, I tie the ends of the steel This invention relates to the classof carbar together, preferably by forming the bar 1o gears which supportthe car-body by bearings with overlapping hook-shaped ends whichinmounted on rings suspended from the axles terlock with each other, asshown in Fig. 2 of of the trucks; and the invention consists, thedrawings, and these overlapping ends I first, in an improvedconstruction of the weld together, as heretofore.

lVhen itis desired to lubricate the bearing of the ring A upon the axle,I provide the check-plate K with the hole 6 above the axles, as shown inFig. 7, and pass a wick through said hole.

The peculiar construction of the brake employed in connection with thedescribed cargear constitutes the subject-matter of another applicationfor Letters Patent filed by me May 9, 1889, Serial No. 310,09i.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

1. In combination with the axle B, ring A, suspended from said axle, andthe roller 0, riding on said ring and supporting the body, the tire T,encompassing said ring, substantially and for the purpose specified.

2. In combination with the axle B, car-bod y,

and roller 0, the ring A, formed of a bar of steel of circular shapejoinedby overlapping interlocking ends, as and for the purpose setforth.

3. In combination with the axle B and bodysupporting roller O, the ringA, formed of a bar of steel of circular shape joined by overlappinginterloeking ends welded together,

and the tire T, encompassing said ring, substantially as described andshown.

4. In combination with the roller O, the hollow journal D, provided withlateral channels r, and with a removable stopper on its end,substantially as described and shown.

5. In combination with the axle B, the check-plates K, provided with aperforation, and lubricant-chambers at the exteriors of saidcheck-plates, substantially as and for the purpose set forth.

In testimony whereof I have hereunto signed my name this 7th day ofFebruary, 1889.
